IPC: B22D27/06
Filed: 1987-09-07
Abstract: PURPOSE:To reduce an electric power cost and to improve the yield of a product by heating and holding the molten steel in a top part by using graphite electrodes in the initial and middle periods of steel ingot production and replacing the electrodes with steel electrodes and diluting the molten steel component in the top part in a late period. CONSTITUTION:The graphite electrodes 2 fixed to the tips of the steel electrodes 16 are molten steel 8 is heated and held in the initial and middle periods of steel ingot production. The steel electrodes 16 are immersed in the slag 12 in place of the graphite electrodes 20 and the dropping molten steel 22 is replenished to the top part of the molten steel 8 by the slag Joule heat generated when electric power is impressed in the late period.

Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To improve a frame rate without reducing dealing charge quantity of a vertical CCD(charge coupled device) at the time of transferring plural lines in one horizontal synchronous period. SOLUTION: In a waveform drawing showing horizontal synchronous timing of a CCD solid-sate image pickup element, a thinning mode is displayed and signal charges are verticality transferred for two lines in one horizontal synchronous period. It is characteristic that an overlap period of respective phases of a vertical transfer clock is taken to be long so that dealing charge quantity is not reduced since plural lines are given. It is preferable that the timing is adjusted to be substantially similar to that at the time of a regular mode when one line is vertically transferred. CLK shows a waveform of a master clock, HD the waveform of a horizontal synchronizing signal (one period), Hϕ1 the waveform of a horizontal CD driving cock, and Vϕ1, Vϕ2 and Vϕ3 the waveforms of the vertical CCD driving clock (three phase transfer driving).
